Define Nos Meaning

Acronym for , Nitrous Oxide Sytems, used for fuel injected cars ( can be used for carbuerated, with a lot more hassle and cussing) to boost the car's acceleration by injecting a pre-determined shot of nitrous oxide into the fuel-air mixture. Doing this creates a feeling similar to turbo-charging your car. This can sometimes be a cheaper alternative to turbo or super chargers. However, nitrous requires refilling whereas turbo does not, so turbo pays off in the long run. Both can create an undesirable high pitched sound commonly heard in briggs and stratton's, I mean 4-bangers. So for a way to increase performance w/out 2-stroke sounds, please see NA

Short for "No One Escapes Death" from Dead by Daylight. Noed is a hex perk which causes all survivors to suffer the "exposed" status effect once the exit gates have been opened, thus causing survivors to die from one hit from the killer as opposed to two hits. Most killers in Dead by Daylight are usually flamed at for "Being carried by noed".

Noun.
1) An acronym for the brand name 'Nitrous Oxide Systems'. NOS produces a chemical known as nitrous oxide, often used in the performance optimization of car and motorcycle engines. The chemical (N2O) breaks up upon contact with air, releasing extra oxygen into the engine. This often means that oxygen detectors in modern cars pick up the extra oxygen and add more fuel to the a/f mixture. This means the engine will pack a harder punch than it typically would, in the form of an instant flywheel horsepower gain.
2) A buzzword used by the illegal street racing comunity (often populated by rice burners), to make one's car sound fast. Many misconceptions have arisen from the term NOS, particularily founded by the film iThe Fast And The Furious/i. One misconception is that NOS can be installed on any car, and with the push of a button it will result in an exponential gain in speed. Another is that NOS iis/i nitrous oxide; NOS is only a brand name. Nitrous oxide can only be installed on some engines, and does not necessarily mean a huge gain in speed. It is NOT activated with the push of a button, most nitrous systems have a throttle trip system that activates the nitrous flow at WOT (wide-open-throttle), in order to maximize potential speed. Another widely mentioned misconception is that nitrous oxide is flammable. It is not. Though any compressed gas can explode when heated, the gas itself is non-flammable.

A recreational drug, often inhaled repetitively with the help of balloons. Causes about 12 seconds of euphoria. Often accompanied by a "womp womp womp womp" sound, not unlike the experience of laughing gas.
